引力波和电磁场作用中扰动光子流的接收面

A Receiving Surface of Perturbative Photon Fluxes in Interaction Between Gravitational Waves and EM Fields

根据弯曲时空中的电动力学,引力波和电磁场相互作用时将产生扰动电磁场。在特定的电磁系统中,即一个在静磁场中传播的高斯光束,如果入射引力波和高斯光束同频并且沿着高斯光束的对称轴Z方向传播,则高斯光束将和产生的扰动电磁场发生最佳同步谐振,导致沿高斯光束电场方向仅仅存在扰动光子流,即扰动电磁能流。详细计算和分析了扰动光子流的一些典型空间分布,找到了一个扰动光子流可能的最佳接收面。计算表明,它接收到的扰动光子流可望达到104s-1量级。这对高频引力波的探测将提供一个新的理论依据。

According to Electrodynamics in curved spacetime, the interaction between gravitational waves (GW) and electromagnetic (EM) fields will produce perturbative electromagnetic fields. In a special EM system, namely, a Gaussian beam (Gb) propagating through a static magnetic field, the photon flux along the direction of the electric field of the Gb will be only a pure perturbative photon flux,when a GW propagates along the symmetric axis of a Gaussian beam. Detailed alanysis and calculation of the photon flux along several typical surfaces are performed, and a possible optimum plane which can receive perturbative photons up to 10~4s^(-1) is proposed. It is possible to provide an important method to detection of GW.
